It says there is no `cluster`. SigNoz needs a cluster named `cluster`. It would be set up automatically unless you took different steps for setting up ClickHouse?

<@U0520QZTRRV> It looks like you are using external ClickHouse helm chart and not that maintained by SigNoz.

There are some pre-requisites for external clickhouse:
• UDF script and histogram quantile binary needed in clickhouse: <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/custom-function.xml|custom-function.xml> and <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/user_scripts/histogramQuantile|histogramQuantile binary>
• must have at least one zookeeper instance
• distributed cluster named `cluster` set up required: <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/clickhouse-cluster.xml|clickhouse-cluster.xml>
• user passed must have enough privileges to create/manage databases in CH
• secure connection not supported between clickhouse and signoz components yet

<@U021J8BQQ0Y> including above in docs would be helpful for anyone using SigNoz with external clickhouse

Noted <@U02SS3ZAMKQ>. Should I create a new page for it here: <https://signoz.io/docs/operate/clickhouse/>

Or can it go under any of the already existing pages?

Yes, it makes sense for it to he under operate/clickhouse
